Club fungi Mushrooms (Coprina #25), shelf fungi, puffballs, rusts and smuts Mycelium may be formed of hyphae that are dikaryotic (2 nuclei) which become a basidiocarp (fruiting body) that releases spores. Following karyogamy and meiosis the basidium produces 4 basidiospores each.

SYMBIOTIC ASSOCIATIONS?

These are NOT taxonomic groups.

Observe specimens (crustose, foliose, fruticose) and slide #27 shows 3 layers. Organisms formed by a symbiotic relationship between unique types of fungi and cyanobacteria or green algae. The relationship between the two is uncertain. Reproductive structures called soredia. The fungal component is extremely difficult to culture separately while the alga grows well alone
